HOUSTON – Early inspections have shown no damage to the space shuttle Discovery, NASA said yesterday after a day of checking out the spacecraft with on-board cameras.

That means that when the shuttle meets up with the international space station this morning it likely won’t need emergency repairs while hooked up with the orbital outpost – unlike last year’s daring spacewalk fixes.

The deputy shuttle program manager, John Shannon, said yesterday evening that the redesigned sections of the external fuel tank held up well during the launch, and that little if any foam came off those areas.

“Overall, the tank performance was really outstanding,” Mr. Shannon, chairman of the mission management team, said.

Yesterday’s inspection by the astronauts uncovered a thermal tile filler poking about a half-inch out of the belly of Discovery. Mr. Shannon said better data should be available yesterday but for now, engineers do not believe the dangling fabric will pose a danger for re-entry or require spacewalking repairs, as it did last summer when two similar strips had to be removed in orbit.

Discovery’s delicate heat shield and everything else appear at first glance to be in near perfect shape, NASA officials said, although it’s still very early in the analysis.

Engineers are nowhere near finished poring over 70 minutes of video that astronauts shot using an extended boom armed with a laser and cameras to inspect Discovery’s delicate reinforced carbon wing and nosecone.

It took Discovery’s crew more than six hours to get 70 minutes of video because they had to move the boom slowly so not to bump the fragile shuttle skin.

In 2003, a piece of foam insulation from the shuttle’s external tank knocked a hole in a wing during launch, causing Columbia to disintegrate as it returned home for a landing.

And last year, film captured damage during the first space flight after Columbia, requiring a special on-the-belly emergency repair spacewalk.

Engineers will painstakingly go over yesterday’s images of Discovery – and others shot by cameras during Tuesday’s launch from various locations – and report any possible losses of foam from the tank or damage points on the shuttle. So far the list of “areas of interest” for possible damage is empty, the lead flight director,Tony Ceccacci, said in an early afternoon news conference.

Launch photos show only five minor cases of debris shedding, all occurring after the shuttle was at such a high altitude there was little air pressure and no force to cause damage, the shuttle program manager, Wayne Hale, said on Tuesday.

“We have a very clean vehicle,” Mr. Ceccacci said.

He also said a pre-launch problem involving a thruster heater should be fixed by this morning, when it’s needed for the delicate dance of docking the shuttle with the space station.The two will stay connected at least until July 14.

The seven-member Discovery crew awoke early yesterday to sounds of “Lift Every Voice and Sing,” sometimes referred to as the black national anthem.

“That one is particularly dear to my heart because … after the day of our nation’s independence, it’s very fitting because it reminds us that anyone and everyone can participate in the space program,” astronaut Stephanie Wilson, only the second black woman in space, radioed to Mission Control.

The mission for Discovery’s crew is to test shuttle-inspection techniques, deliver supplies to the international space station, and drop off a European Space Agency astronaut, Thomas Reiter, for a six-month stay. Astronauts Piers Sellers and Michael Fossum plan to carry out two spacewalks, and possibly a third, which would extend the 12-day mission by a day.
